Behind one of these doors there’s a brand new car. Behind the other two are goats. You get to pick a door. Then, the host will open one of the doors you didn't open to reveal one of the goats. He asks you: ‘Do you want to switch doors, or are you staying with the door you chose?’ What do you do? “.

Probability Questions & Answers

There are 6 red, 4 green, 5 blue and 5 yellow marbles in a jar. What is the probability of picking a green marble, then a blue marble if you do not put back the first marble?
1/19Find the probability of picking green (4/20), then find the probability of picking blue (5/19). Remember there is one less marble in the jar. Finally multiply the probabilities and reduce to get 1/19
What would be the experimental probabililty of the coin landing on heads if it is ossed 50 times, and it lands on heads 28 times?
The correct answer is 14/25. The proportion of heads in this experiment will be equal to the total number of favorable events (i.e. heads) divided by the total number of events (i.e. heads+tails). By this formula, we shall get : 28/ (28 + 22) = 28/5
